Abstract

A sheet attachment detecting apparatus includes a rotary member which is rotatable for conveying a sheet and whose surface is electrically conductive, an electrically conductive member which can be abutted on and separated from the surface of the rotary member, and an attachment detector which applies a power to the rotary member and the electrically conductive member for detecting the attachment of the sheet around the rotary member.
